Hi to all, I'm searching for a pseudopotential for TPSS calculations. Has anyone done it for H, C, N and O? Is PBE pp (which is used in J. VandeVondele et al. J.Chem.Phys. 122, 014515 (2005)) a reasonable choice for TPSS calculation or better use another pp? Thanks in advance, Alex Kargovsky Faculty of Physics Moscow State University
